Step-by-step explanation: To find the inverse function of a one to one function, we switch x and y and then solve for y.
For the function y = x, following that procedure gives us y = x again.
So, f-1(x) = x
Therefore, f-1(g(x)) = f-1(2x) = 2x
f-1(g(x)) = 0.25 yields 2x = 0.25
2x = 1/4
2x = 2-2
x = -2
